[ARC5] Band noise (Was dynos and receivers)

[Bob Macklin]

The Timewave unit is the ANC-4. I have on and it does work.

But it does not make signals where there are no signals.

There are RBNs at Vancouver, BC, about 30 miles south of Seattle, Eureka, 
Ca, and several in the SF Bay Area. None seen so show any 80M activity at 
night.

There are also several in the So Cal area.
